The location information of the UWB tag may be used to characterize the location of the target user, such as installing a UWB positioning base station in the target area, carrying the UWB tag on the target user, and using the UWB positioning base station and the UWB tag to position the target user to move from a first location to a second location (i.e., location information) when the target user moves within the target area, the first location and the second location being located within the target area.
And step S204, adjusting the working parameters of the intelligent device according to the position information of the UWB tag.
The purpose of adjusting the working parameters of the intelligent device is to transfer the sound effect applicable area of the intelligent device from the first sub-area where the first position is located to the second sub-area where the second position is located, and the target area comprises the first sub-area and the second sub-area.
In the related art, when a user is positioned and identified, the positioning can be realized by installing human body identification devices such as an infrared induction probe, an ultrasonic induction probe and the like in a sound field, but the positioning methods have low transmission rate and low precision, when the user is in a motion state, the user cannot obtain accurate positioning in real time, and the user cannot obtain optimal listening experience.

The UWB technology is a wireless technology based on extremely narrow pulses, does not need to use carrier waves in a traditional communication system, and transmits data by sending and receiving the extremely narrow pulses with nanosecond or below, so that the bandwidth of 3.1-10.6GHz level is achieved, the advantages of high transmission speed and high positioning precision are achieved, the problems of low transmission speed and low precision of a positioning method in the related technology can be solved, the position of a user can be quickly and accurately positioned along with the improvement of the positioning speed and precision, the sound effect can be quickly adjusted, and the sound effect experience of the user can be improved.
UWB indoor location technology often employs TDOA to demonstrate ranging location algorithms, i.e., ultra-wideband systems that locate by time difference of arrival of signals, by hyperbolic crossings, include radio systems that generate, transmit, receive, process very narrow pulse signals. Compared with the traditional narrow-band system, the ultra-wide-band system has the advantages of strong penetrating power, low power consumption, good multi-path resisting effect, high safety, low system complexity, capability of providing accurate positioning precision and the like. Therefore, the ultra-wideband technology can be applied to positioning, tracking and navigation of indoor stationary or moving objects and people, and can provide very accurate positioning precision. The scheme is realized by adopting the UWB technology, the position of a user can be accurately acquired, and the listening effect is further optimized. The technical scheme of the application is further detailed below by combining specific steps, taking intelligent equipment as an example of a sound device:
step 1, a plurality of UWB positioning base stations (which can be set in a sound box) are arranged indoors, and a user carries with the intelligent equipment (such as a chest card, a mobile phone and the like) provided with a UWB tag.
And 2, dividing a target area where the sound field is located into a plurality of sub-areas.
For each sound effect, such as blue tone, heavy bass, country music, etc., the working parameters (such as volume, loudness, frequency, etc.) of each sub-area are generated according to the best listening effect, and further the configuration information is generated, in which each sound effect can correspond to a record, and in this record, the working parameters of each sub-area are recorded.
And 3, positioning the target user to be transferred from the first position to the second position by using the UWB positioning base station and the UWB tag.
In the method, a Time Of Flight (TOF) method is used for ranging between the UWB positioning base station and the UWB tag, and the distance between the UWB positioning base station and the UWB tag is measured mainly by using the Time Of Flight Of signals between two asynchronous transceivers (transceivers), specifically, a two-way Time Of Flight method (TW-TOF) is used, for example, a transmitter Of the UWB positioning base station transmits a pulse signal Of a request property when the Time stamp is Ta1, the UWB tag transmits a signal Of a response property when receiving the signal, the UWB positioning base station receives the pulse signal when the Time stamp is Ta2, and the Time Of Flight (Ta 2-Ta 1) Of the pulse signal between the UWB positioning base station and the UWB tag can be calculated, so that the interval between the UWB positioning base station and the UWB tag is determined to be S = (Ta 2-Ta 1) × P/2, and the UWB P is the Flight speed.
The number of the UWB positioning base stations is at least three, the distances S1, S2, and S3 between the three UWB positioning base stations and the UWB tag can be measured at the same time, the coordinates of the UWB tag can be assumed to be (x, y, z), and the coordinate values of the UWB tag can be calculated by combining the three equations.
The first position and the second position can be calculated according to the scheme.
And 4, adjusting working parameters of the intelligent sound box to transfer the sound effect application area of the intelligent sound box from the first sub-area where the first position is located to the second sub-area where the second position is located.
Assuming that when the user is in the first sub-area, the sound effect of the smart sound box is the first sound effect (which may be the default sound effect of the current music or set by the user), and the used first working parameter is obtained from the first record matched with the first sound effect in the configuration information according to the area tag of the first sub-area.
When the sub-area where the user is located is switched from the first sub-area to the second sub-area, the processing can be performed in two cases, one of which is that the sound effect of the smart sound box is not changed (i.e. the song switching does not occur or the sound effect is not switched by the user), and at the moment, the second working parameter can be continuously obtained from the first record according to the area label of the second sub-area; and secondly, the sound effect of the intelligent sound box is changed (namely, the song switching or the sound effect switching by the user occurs), at this moment, a second record matched with the second sound effect is searched from the configuration information according to the switched second sound effect, and then a second working parameter is obtained from the second record according to the area label of the second sub-area.
Optionally, during adjustment, a first time when adjustment starts and a second time when adjustment ends may be obtained; and at any third moment between the first moment and the second moment, controlling the intelligent sound box to work according to third working parameters, wherein the value of each type of working parameters in the third working parameters = the value of the same type of parameters in the first working parameters + (the value of the same type of parameters in the second working parameters-the value of the same type of parameters in the first working parameters) (the third moment-the first moment)/(the second moment-the first moment).
For example, the first time (0 hours 0 minutes 0 seconds) corresponds to a loudness of 50, the second time (0 hours 0 minutes 4 seconds) corresponds to a loudness of 90, and the third time (0 hours 0 minutes 3 seconds) corresponds to a loudness of 80.
By adopting the technical scheme, the sound effect heard by the user can be prevented from changing suddenly to cause discomfort by adjusting in a gradual change mode, and the user experience is further improved.
